取得JSON格式的頁面資訊 obtaining-page-information-in-json-format
若要取得頁面資訊，請傳送要求至PageInfo servlet以取得JSON格式的頁面中繼資料。
PageInfo servlet會傳回存放庫中資源的相關資訊。 此servlet已繫結至URL https://<server>:<port>/libs/wcm/core/content/pageinfo.json 並使用 path 用於識別資源的引數。 以下範例URL會傳回關於 /content/we-retail/us/en 節點：
http://localhost:4502/libs/wcm/core/content/pageinfo.json?path=/content/we-retail/us/en
頁面資訊提供者 page-information-providers
頁面元件可以關聯至一或多個 com.day.cq.wcm.api.PageInfoProvider 產生頁面中繼資料的服務。 PageInfo servlet會呼叫每個PageInfoProvider服務，並彙總中繼資料：
- HTTP使用者端傳送要求給PageInfo servlet，其中包含頁面的URL。
- PageInfo servlet會找出轉譯頁面的元件。
- PageInfo servlet會呼叫與元件相關聯的每個PageInfoProvider。
- 此servlet會彙總每個PageInfoProvider傳回的中繼資料，並將中繼資料新增至JSON物件的HTTP回應中。
NOTE
與PageInfoProviders類似，使用ListInfoProviders更新JSON格式的資訊清單。 (請參閱 自訂網站管理主控台.)
預設頁面資訊提供者 default-page-information-providers
此 /libs/foundation/components/page 元件與下列PageInfoProvider服務相關聯：
- 預設頁面狀態提供者： 頁面狀態的相關資訊，例如是否已鎖定、頁面是否為作用中工作流程的裝載，以及頁面可用的工作流程。
- 即時關係資訊提供者： 有關多網站管理(MSM)的資訊，例如頁面是否為Blue Print的一部分，以及是否為即時副本。
- 內容語言Servlet： 目前頁面的語言，以及該頁面可用的每種語言的相關資訊。
- 工作流程狀態提供者： 有關將頁面作為承載的執行中工作流程的狀態資訊。
- 工作流程封裝資訊提供者： 有關儲存於存放庫中的每個工作流程封裝的資訊，以及每個封裝是否包含目前的資源。
- 模擬器資訊提供者： 此資源可用的行動裝置模擬器相關資訊。 如果頁面元件未轉譯行動頁面，則沒有可用的模擬器。
- 註解資訊提供者： 有關頁面上註解的資訊。
例如，PageInfo servlet針對 /content/we-retail/us/en 節點：

篩選工作流程封裝資訊 filtering-workflow-package-information
設定Day CQ WCM Workflow Package Info Provider服務，使其僅傳回您感興趣之工作流程套件的資訊。 依預設，Workflow Package Info Provider服務會傳回存放庫中每個Workflow套件的資訊。 反複處理工作流程套件的子集會使用較少的伺服器資源。
NOTE
Sidekick的「工作流程」標籤會使用PageInfo servlet來取得工作流程封裝清單。 從清單中，您可以選取要新增目前頁面的封裝。 您建立的篩選器會影響此清單。
服務的ID為 com.day.cq.wcm.workflow.impl.WorkflowPackageInfoProvider. 若要建立篩選器，請為 workflowpackageinfoprovider.filter 屬性。
屬性值會加上前置詞+或 — 字元，後面接著套件路徑：
- 路徑是Workflow套件的根節點的路徑。 路徑使用FileVault語法。
- 若要包含套件，請使用+前置詞。
- 若要排除套裝程式，請使用 — 前置詞。
此服務會套用所有篩選器的累積結果。 例如，下列篩選值會排除所有工作流程封裝，Editions資料夾中的除外：
-/etc/workflow/packages(/.*)?
+/etc/workflow/packages/Editions(/.*)?
NOTE
使用AEM時，有數種方法可管理此類服務的組態設定。 另請參閱 設定OSGi 以取得完整詳細資訊。
例如，若要使用CRXDE Lite設定服務：
-
開啟CRXDE Lite(http://localhost:4502/crx/de)。
-
在應用程式的設定資料夾中，建立節點：
- 名稱：
com.day.cq.wcm.workflow.impl.WorkflowPackageInfoProvider - 類型：
sling:OsgiConfig
- 名稱：
-
選取節點並新增屬性：
- 名稱：
workflowpackageinfoprovider.filter - 類型：
String[] - 值：使用正確格式的工作流程封裝路徑。
- 名稱：
-
按一下「儲存全部」。
若要在專案來源中設定服務：
-
在您的專案來源中找到或建立AEM應用程式的設定資料夾。
例如，如果您使用Content Package Maven外掛程式的multimodule原型來建立您的專案，資料夾路徑為
<projectroot>/content/src/ for example, content/src/main/content/jcr_root/apps/<appname>/config. -
在設定資料夾中，建立名為com.day.cq.wcm.workflow.impl.WorkflowPackageInfoProvider.xml的文字檔
-
將下列文字複製到檔案中：
code language-none <?xml version="1.0" encoding="UTF-8"?> <jcr:root xmlns:sling="https://sling.apache.org/jcr/sling/1.0" xmlns:jcr="https://www.jcp.org/jcr/1.0" jcr:primaryType="sling:OsgiConfig" workflowpackageinfoprovider.filter="[]"/> -
在方括弧內(
[])周圍的workflowpackageinfoprovider.filter屬性中，輸入類似下列範例的逗號分隔篩選值清單：workflowpackageinfoprovider.filter="[-/etc/workflow/packages(/.*)?,+/etc/workflow/packages/Editions(/.*)?]"/> -
儲存檔案。
建立頁面資訊提供者 creating-a-page-information-provider
建立自訂頁面資訊提供者服務，新增您的應用程式可輕鬆取得的頁面中繼資料。
-
實作
com.day.cq.wcm.api.PageInfoProvider介面。 -
將類別捆綁並部署為OSGi服務。
-
在應用程式中建立頁面元件。 使用
foundation/components/page作為sling:resourceSuperType屬性。 -
在元件節點底下新增名為的節點
cq:infoProviders. -
在
cq:infoProviders節點，為您的PageInfoProvider服務新增節點。 您可以為節點指定任何名稱。 -
將下列屬性新增至您的PageInfoProvider節點：
- 名稱： className
- 型別：字串
- 值： PageInfoProvider服務的PID。
針對使用應用程式頁面元件作為的資源 sling:resourceType，除了預設的PageInfoProvider中繼資料外，PageInfo servlet還會傳回自訂PageInfoProvider中繼資料。
PageInfoProvider實作範例 example-pageinfoprovider-implementation
下列Java類別實作 pageinprovider 和會傳回目前頁面資源的已發佈URL。

public void updatePageInfo(SlingHttpServletRequest request, JSONObject info, Resource resource)

Page page = resource.adaptTo(Page.class);
JSONObject urlinfo = new JSONObject();
urlinfo.put("publishURL", fetchExternalUrl(null,page.getPath()));
info.put("URLs",urlinfo);
}
}
以下範例以CRXDE Lite顯示設定為使用PageUrlInfoProvider服務的頁面元件：
PageUrlInfoProvider服務傳回以下資料 /content/we-retail/us/en 節點：
"URLs": {
"publishURL": "http://localhost:4503/content/we-retail/us/en"
}
